NOTE: We receive a lot of emails about the compatibility of these
stems with their bikes. This stem fits handlebars that are 1" in
diameter where the stem clamps. Where it inserts into the fork, it
measures the same at 22.2mm or 7/8". It's intended for 1" threaded
steertubes with an inner diameter of 22.2mm. It is important not to
confuse this stem with the other popular size, 25.4mm (1") intended for
1-1/8" threaded steertubes.
